Abstract: The disclosure relates to a 5th generation (5G) or 6th generation (6G) communication system for supporting a data transmission rate higher than a 4th generation (4G) communication system such as long term evolution (LTE). A user equipment (UE) in a communication system is provided. The UE includes a transceiver, and a controller configured to receive, from a base station, system information including information related to transmission of a random access preamble, and to transmit, to the base station, a physical random access channel (PRACH) including the random access preamble. The PRACH includes at least one primary signal part including a first sequence for measuring a first delay within a symbol, and at least one secondary signal part including a second sequence for measuring a second delay in units of symbols, and a round trip delay (RTD) between the UE and the base station may be determined based on the first delay within the symbol and the second delay in units of symbols.

Abstract: Disclosed is a method performed by a reconfigurable intelligent surface (RIS) device, the method including configuring a number of fixed beams for a beam, a fixed reflection pattern for the beam, and a fixed period for the beam; and reflecting a signal based on the number of the fixed beams, the fixed reflection pattern, and the fixed period, with the fixed reflection pattern being related to an amplitude and a phase of the reflected signal.

Abstract: The present disclosure relates to technologies for sensor networks, machine to machine (M2M) communication, machine type communication (MTC), and Internet of Things (IoT). The present disclosure may be utilized for intelligent services based on the above technologies (smart homes, smart buildings, smart cities, smart or connected cars, health care, digital education, retail businesses, security and safety-related services). The present invention relates to a method and apparatus that, when a user equipment notifies its identification information using an unsecured connection, enable the user equipment to notify the identification information in a secure manner using a one-time password (OTP) algorithm and proximity authentication and to receive services customized to user needs.
